This discussion focuses on plotting velocity as a function of time in VPython, a 3D graphics library for Python. Users noted that while VPython documentation primarily covers position plotting, velocity can be derived from position data. To plot velocity, one must compute the derivative of the position function with respect to time or calculate numerical derivatives from position data arrays. The conversation emphasizes the need for users to perform these calculations manually, as VPython does not automate this process.
PREREQUISITESThis discussion is beneficial for Python developers, educators in physics, and anyone interested in visualizing motion through velocity plotting in VPython.
I don't understand your quandary. If you are able to plot position vs. time, why can't you also plot velocity vs. time? I'm not familiar with vpython, but it seems to be concerned mostly with 3D plots. If all you need is a 2D graph, you might consider using matplotlib with Python.e2m2a said:Summary:: Can't find any documentation on how to plot/graph velocity as a function of time in vpython.
Can someone tell me how to plot/graph velocity in vpython? All the documentation I see just deals with plotting the position of the object, nothing on plotting the velocity.
My assumption was that the velocities at the various times were known.robphy said:Given the position as a function of time, you need to somehow compute the velocity as a function of time.
